App Store, Pages 5.0, Evernote, and other Apps will not fully function after installing Mavericks. What is the issue and how can this be solved?

Question

Hello all, I could use some serious help on some major issues I have been having after installing Mavericks on my system (specs stated below). Never has a mac felt ever so rebelious and broken before in my lifelong period of using these systems. Anyway, after installing system 10.9, I had opened the mac App Store upon seeing that applications such as my iWork suite all had free updates. However, when I would attempt to navigate to the updates window, it would not respond to my various attempts. I then tried to get there by the system's menu bar and to my dismay, nothing would work when I clicked on it, not even the apple logo menu. I later quit the application using Command-Q and opened up the App Store by the apple menu option 'Software Update...' instead. Though it looked promising since the updates window did open, all update buttons or even '...more' info buttons were unresponsive.  These same problems persisted even after restarting my computer. I had also attempted to see if repairing definitions would help by booting from the recovery start-disk and using disk utility but the repairs it carried out apparently had nothing to do with my issue. Finally, I was able to update to the new iWorks suite (which interestingly did not replace the iWorks '09 suite) by following the notification that asked about allowing automatic updates which I did.
Once trying to use Pages 5.0, I soon noticed that all I could do was merely type in a new document and change various options via key commands. Neither the inspector or top bar menus would respond to any place I click. Similarly, Evernote only starts up on the last used note and merely allows me to scroll through it. The top bar menus, the note select pane, and even clicking inside the note to input text are all not functioning and uninfluenced by any mouse clicks.
I have noticed other apps that will not respond to any sort of input, but I still have not explored all applications to know what the issues of each may be. However there are some applications that work such as Safari, Google Chrome, dolphin, iWork '09 including Pages '09, and others.
I do hope that I can avoid rolling back my system, but in the meantime, it has been quite the obticle course to use my computer for all of my school purposes.
Any help is very much appreciated,
Thank you!

I also forgot to note that this problem also persists with the new iBooks application. I cannot get past the 'Get Started' screen or access the iBooks Store. Again, all top bar menus are unresponsive.
